UNITED STATES RALPH M. JACKSON, OF LA HABRA, CALIFORNIA.

FUMIGATING APPLICATOR.

Application led November 20, 1922. Serial No. 602,317.

T all whom it may concern.:

Be it known that I, RALPH M. JACKSON, a citizen of the United States, residing at La Habra, in the county of Orange and State of California, have invented a new and useful F umigating Applicator, of which the following is a specification.

My invention relates to measuring devices and gasitiers for applying liquid gases for umigating purposes under covered trees.

Among the objects of this invention is to provide .suitable means in a device of this character whereby lever means for producing ressure may be employed with a ver tical y disposed pump measuring means and means whereby a series of fixed measurements may be measured and discharged in intermittent expulsions from said pump means through discharge nozzle means being laterally spaced from and in approximate horizontal alignment with the lower end of said pump means and at an appreciable distance from said pump means.

Other objects may hereinafter appear.

The accompanying drawings clearly illustrate the structure.

Fig. 1 of the drawings is a side elevation of my device with portions of the structure cut away for clearness including a portion of the supply receptacle and showing in section the pump mechanism associated therewith. f

Fig. 2 is an enlarged sectional detail of the vaporizing nozzle means and showing the fiuid controlling means associated therewith for controlling the free How of fluid through the nozzle.

\Fig. 3 is a front end view of the supply receptacle and of the mechanism associated therewith.

Fig. 4 is a back end view of the supply receptacle and the mechanism associated therewith and illustrates in detail the measure controlling member and the association thereof withthe level' actuating member.

Fig. 5 is an enlarged sectional detail ofthe pump plunger and pump valve mechanism with compressionl ring in place but with plunger packing material not shown.

In detail construction the device comprises a supply receptacle 1 for fumigating material. A pump cylinder 2 connected at its upper end through the collar 3 to the bottom of receptacle 1, and at its lower end is connected to a pump base 4 which is in turn connected to a base board 5. A pump plunger 6 working in the cylinder 2 and provided with the compression ring 6"l is provided with a central valve mechanism comprising a ball 7 and a seat 8 situated at the upper end of plunger 6, a piston rod 9 exltends downwardly through ball 7 and through the plunger 6 forming a guide therefor, screw adjustin` means 10 is provided at the lower end o piston rod 9. Piston rod 9 extends upwardly from plunger 6 and through a stufling box 1l provided at the top of receptacle 1 and is pivotally connected at its upper end to the lower end of a connecting rod 12 which is pivotally connected at its upper end to a lever actuating member 13, the same being pivotally connected to the upper end of an upright support'14 which support projects downwardly Vand around one slde of receptacle 1 to the base 5 and is securely attached thereto at its lower end. An upright support A15 is attached'at its lower end to base 5 and projects upwardly and around the side of receptacle 1 to a point-.above said receptacle 1 and forms a su port at its upper end for one end of a handle 16 which is provided for carrying the device. Screws 17, 18, 17al and 18a form a tie between-the supports 14, 15, 19 and 21 above and below receptacle 1. Upright support 19 is secured at its lower end to base 5 and extends upwardly to receptacle 1 and around same to a point above the receptacle forming part of a' support for a measure controlling member 2O and supports one end of handle 16. Upright support 21 which also Vsupports controlling member extends downwardly from said member 2O around one side of receptacle 1 to hase 5 and is secured thereto at its lower end. Fluid conducting means 22 is connected at one end to the lower end of pump cylinder 2 and projectslaterally therefrom and at the other end connects with vaporizing nozzle means 23. A ball valve 24 is provided in the nozzle means23 for controlling the free How of fluid through the nozzle and is opened by pressure flow of fiuid, a spring 25 closes the valve when pressure is oil". A screw plug 26 is provided in the top of nozzle means 23 and has a guide pin extension 27 which forms a guide for spring 25. A filler port 28 having the cap 29 is provided in the top of receptacle 1. Adjusting screws 30 and 31 are -provided for the measure controlling member 20. Vent line 32 which is connected atts upper end to a. vent chamber 33 at tho top of receptacle 1 projects downwardly to a point in horizontal alignment with discharge line 22 and thence laterally -to .a point adjacent the nozzle means 23. Lever 13 is provided with a boss member 34 which is adapted to engage with the shoulder 35 of the controlling member 20. The device is operated b the handle 36. A glass tube 37 is provide for determining the quantity of li uid in the supply receptacle.

n operating the device the measurement of Huid is accomplished with a uniform stroke of the actuating lever 13, controlled by thc measure controlling member a full stroke accomplishing the measurement of five units, the measurement of one unit being accomplished by springing the actuating i lever 13 to the right causing the boss member 34 on the side of the actuating member to engage with the shoulder 35 of the measure controlling member. For example, if a measurement of eleven units were desired the operator would raise the actuating lever until it engaged with the controlling member screw 30, the action would raise the ball valve 7 slightly, through lost motion in the valve mechanism but-sufficient to permit the space in the ump cylinder below the plunger to fill, t e operator would then throw the lever downwardly causing the ball valve to close and a continuation of ,such downward movement until the actuating lever engaged with the controlling member screw 31 would cause the expulsion from the pump of five units of fiuid, a repetition of such operation would accomplish the measurement of ten units and it would then re= quire the employment of the means pro'- vided for the measurement of one unit to accomplish the measurement of the eleven units. Other measurements of different denominations would be accomplished in the same manner using the one unit measure from the pump through the nozzle with suficient pressure to convert the fluid into vapor. he valve 24 by checking the free Hpw of fluid from the line 22 provides means whereby a series of fixed measurements may be ,measured and discharged in intermittent expulsions from the pump means through the nozzle means.

Although the device is illustrated in the present preferred construction it is to be understood that various detail alterations in the structure within the skill of the work men may be made without departing from the scope of the invention.

Having` thus described my invention, I claim:

A fumigating applicator including a supply receptacle for fumigating fluid, base means, supporting means attached to said base means and projecting upwardl from said base means to a point above saidyreceptacle, vertically disposed pump measuring means for measuring said fiuid the measure- .ment thereof representing a plurality of units, a horizontally disposed actuating lever for said pump means supported by said supporting means, a measure controlling member for controlling the said actuating member and for determining the unit measurement of the 'said measuring means, vaporizing discharge nozzle means laterally spaced :from the said measuring means and Huid conducting means connecting said nozzle means ,with the said measuring means, fluid controlling means associated with `the said nozzle means and adapted to control the free fiow of fluid through the said nozzle means.

In 'testimony whereof I hereunto afiix my signature in the presence of two witnesses. 8:5
